Summary Introduction
To analyze:
The diagram and labeling of the structures of the heart.
Introduction:
The process of blood circulation is conducted by the heart and blood vessels. The pumping action of the heart occurs due to the onset of cardiac muscle contractions. The blood is then transported by the blood vessels.
